do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

You can access the HTML version of this tutorial here: https://redhat-scholars.github.io/kubernetes-tutorial/
## Visual Studio Code Remote Development
If you are using link:https://code.visualstudio.com/[Visual Studio Code] with the link:https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers[Remote Containers Extension], you don't need to install anything locally to be able to contribute or run through this tutorial.
Simply follow these instructions:
1. (Only if running with podman) Set the environment variable `DEVCONTAINER_TARGET_PREFIX=podman`
2. Open VS Code from the root of the `kubernetes-tutorial` repository and when prompted indicate that you want to "open the folder in a container".
Once the devcontainer is initialized, from the Visual Studio Code terminal you will be able to run all the commands outlined for creating documentation.
### Execute Tutorial with VSCode Remote
You can also run through the tutorial with VSCode Remote. The only trick is that you will need to be able to access minikube from within your docker container.
## Building the HTML locally
In the root of your git repository, run:
```
bin/build-site.sh
```
And then open your `gh-pages/index.html` file:
```
open gh-pages/index.html
```
## Iterative local development
You can develop the tutorial docs locally using a rapid iterative cycle.
First, install the `yarn` dependencies:
[source,bash]
----
yarn install
----
And now start `gulp`. It will create the website and open your browser connected with `browser-sync`. Everytime it detects a change, it will automatically refresh your browser page.
[source,bash]
----
gulp
----
You can clean the local cache using:
[source,bash]
----
gulp clean
----

Download and install go

go build myrest.go
then run the compiled executable
./myrest
curl localhost:8000/hello
ctrl-c
Note: go compiles to native and if you have been using a Mac/Windows
you likely need to recompile the binary
env GOOS=linux GOARCH=amd64 go build myrest.go
docker build -t burr/mygo:v1 .
docker run -it -p 8000:8000 burr/mygo:v1

# pizza-operator project
This project uses Quarkus, the Supersonic Subatomic Java Framework.
If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
## Running the application in dev mode
You can run your application in dev mode that enables live coding using:
```
./mvnw quarkus:dev
```
## Packaging and running the application
The application can be packaged using `./mvnw package`.
It produces the `pizza-operator-1.0.0-SNAPSHOT-runner.jar` file in the `/target` directory.
Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/lib` directory.
The application is now runnable using `java -jar target/pizza-operator-1.0.0-SNAPSHOT-runner.jar`.
## Creating a native executable
You can create a native executable using: `./mvnw package -Pnative`.
Or, if you don't have GraalVM installed, you can run the native executable build in a container using: `./mvnw package -Pnative -Dquarkus.native.container-build=true`.
You can then execute your native executable with: `./target/pizza-operator-1.0.0-SNAPSHOT-runner`
If you want to learn more about building native executables, please consult https://quarkus.io/guides/building-native-image.

// See antora yaml (such as github-pages.yml) to change what attribute docker-host is set to
== Prerequisite
In this section, we are assuming you are running Docker in your local machine (either using Docker Tools or native Docker).
IMPORTANT: To make it work correctly, you need to run this section in a new terminal window to avoid using the Kubernetes (`minikube`) environment used in previous sections.
== Build your application artifact
First let's take a quick look at the application we're looking to build
:quick-open-file: MyRESTController.java
include::partial$tip_vscode_quick_open.adoc[]
.MyRESTController.java
image::hello-world-app.png[]
Compile, build and test the Spring Boot Java project:
[#build-building-images]
[.console-input]
[source, bash, subs="+attributes"]
----
cd apps/helloworld/springboot
mvn clean package
java -jar target/boot-demo-1.0.0.jar
----
Then `curl` it in a separate terminal:
[.console-input]
[source, bash]
----
curl localhost:8080
----
[.console-output]
[source,bash]
----
Aloha from Spring Boot! 1 on unknown
----
`unknown` because the environment variable is not currently set, it will be inside of a Docker container and inside of Kubernetes.
== Build container image
NOTE: Change `quay.io` for your registry (e.g. `docker.io`) and `{myrepo}` to your organization. This next step does assume you have a working installation of Docker for Mac/Windows/Linux.

= Operators
include::_attributes.adoc[]
:watch-terminal: Terminal 2
:log-terminal: Terminal 3
:section-namespace: pizzahat
Operators are a way of extending the functionality of our Kubernetes cluster by installing automated controllers to manage extensions we provide to the underlying Kubernetes API.
In this section we'll take a deeper look at how operators interact with the Kubernetes API to do this
.Operators in the Real World
****
When demonstrating this tutorial in a master class, it can be good to show the Kafka Operator in Openshift (as roughly outlined <<Kafka for OpenShift,here>>). Key Points when showing on an OpenShift cluster:
. Use OperatorHub to show how many different Operators there are.
. Install the `AMQStreams` or `Strimzi` Operator to add Kafka support (i.e. CRDs as we'll see) to the cluster
. Once the operator is installed, pick a namespace to install a `Kafka` CR in
. Show in the Developer Perspective the Kafka being created by the operator
In this section of the tutorial we'll be demonstrating these aspects of operators with a home grown toy "Pizza Operator"
****
== Preparation
=== Namespace
We'll need a namespace where we're house our operator deployment and our `CustomResources` upon which the operator will operate
[.console-input]
[source,bash,subs="+macros,+attributes"]
----
kubectl create namespace {section-namespace}
kubectl config set-context --current --namespace={section-namespace}
----
=== Watch
If it's not open already, you'll want to have a terminal open (call it *{watch-terminal}*) to watch what's going on with the pods in our current namespace
:section-k8s: crd
include::partial$watching-pods-with-nodes.adoc[]
=== Logs
We'll want to open a third terminal (call it *{log-terminal}*) where we'll use a tool called `stern` to watch the output of certain pods
include::partial$open-terminal-in-editor-inset.adoc[]
:stern-namespace: {section-namespace}
:stern-pattern: p-pod
:section-k8s: crd
include::partial$stern-watch.adoc[]
== CRDs
Custom Resources extend the API
Custom Controllers provide the functionality - continually maintains the desired state - to monitor its state and reconcile the resource to match with the configuration
https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/
https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/
Custom Resource Definitions (CRDs) in version 1.7
CRDs extend the Kubernetes API. We can see these api resources readily:

<.> This list has been truncated
OpenShift is at its heart Kubernetes. One of the main ways OpenShift extends Kubernetes is via CRDs, which explains why you find so many of them installed even on the back of a fresh installation.

====
=== Example CRD
:quick-open-file: pizza-crd.yaml
Let's go ahead and create our own Custom Resource Definition. Later on, this Custom Resources created from this definition will be something that our operator will operate upon. Take a look at `{quick-open-file}` to see what the CRD we'll be creating looks like
include::partial$tip_vscode_quick_open.adoc[]
[source, yaml]
.{quick-open-file}
----
include::example$pizza-crd.yaml[]
----
<1> This is a description that will be shown when somebody attempts to describe the CRD
<2> This describes one of the values our `CustomResource` will have, namely, the (`array`) list of (`string`) toppings
<3> This describes the second field our `CustomResource` can define in its spec, the (`string`) name of the sauce to use
<4> This is the name that our CustomResources will have. Sort of like `Deployment` or `Pod`
[IMPORTANT]
====
Many CRDs include metadata about the fields that are exposed so that the CR can be validated by the Kubernetes API. Prior to API version `v1` this was not enforced, after Kubernetes v1.22 all `CustomResources` will need to be `v1` and thus will need to define their object schema
====
Now let's go ahead ad add this CRD to our cluster so that we can create `Pizza` Custom Resources.
[.console-input]
[source,bash,subs="+macros,+attributes"]
----
kubectl apply -f apps/pizzas/pizza-crd.yaml
----
We should now be able to see that our CRD is part of our API
[#get-pizzas-crds]

[source,bash,subs="+macros,+attributes"]
----
kubectl get crds | grep pizza
----
Results:
[.console-output]
[source,bash]
----
NAME CREATED AT

[source,bash,subs="+macros,+attributes"]
----
kubectl api-resources | grep pizzas
----
Yields:

----

DESCRIPTION:
A custom resource for making yummy pizzas #<.>
FIELDS:
apiVersion <string>
APIVersion defines the versioned schema of this representation of an
object. Servers should convert recognized schemas to the latest internal
value, and may reject unrecognized values. More info:
https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind <string>
Kind is a string value representing the REST resource this object
represents. Servers may infer this from the endpoint the client submits
requests to. Cannot be updated. In CamelCase. More info:
https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
metadata <Object>
Standard object's metadata. More info:
https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
sauce <string> #<.>
The name of the sauce to use on our pizza
toppings <[]string> #<.>
List of toppings for our pizza'
----
<.> Notice that this matches our overall description of the pizza
<.> This is from the Schema section of the CRD for sauce. It says that it's a string. The description comes from the description field
<.> This is from the Schema section of the CRD for toppings. It says that it's an array of strings. The description comes from the description field
=== Deploying the Operator
Our CRD is not limited to a particular namespace, but we do need a namespace to put our operator that is going to operate on our `pizza` CRs.
At its heart, an operator is just an application, like the `myboot` application that we deployed previously. The difference is that the operator knows to to interact with the Kubernetes API and watch for resources that it cares about.
:quick-open-file: PizzaResourceWatcher.java
The Pizza operator that we're about to deploy was written in link:https://quarkus.io/[Quarkus^] using the link:https://github.com/java-operator-sdk/java-operator-sdk[java operator sdk^]. The code for this operator is present in this repo. See the `{quick-open-file}` which is one of the key classes in the operator controller:

=== Make some Pizzas
Once our operator is running, it will be on the lookout for information in our `Pizza` Custom Resources and use it to (pretend to) make some pizzas by spinning up a pod configurated with information from the Custom Resource instance.
For example, consider this instance of the Pizza `CustomResourceDefinition`:

= DaemonSets
include::_attributes.adoc[]
A DaemonSet ensures that all nodes run a copy of a Pod.
As nodes are added to the cluster, Pods are added to them automatically.
When the nodes are deleted, they are not rescheduled but deleted.
So DaemonSet allows you to deploy a Pod across all nodes.
== Preparation

The exec command allows you to "shell into" your pod and execute commands inside of that tiny linux machine that is running your application.
You can execute it this way:
[.console-input]
[source,bash]

Or this way:
[.console-input]
[source,bash]

No wonder the JVM reports a larger than accurate Max memory:

----
Now check the actual `cgroups` settings:
[#cat-cgroup-exec]

[source, bash]
----
cd /sys/fs/cgroup/memory/
cat memory.limit_in_bytes

And if you divide that 419430400 by 1024 and 1024, you end up with the 400 that was specified in the deployment YAML.
